CRL SPS Self-Guiding Corners and Intersections are designed to easily guide the panels through an infinite variety of configurations and parking conditions to meet your specific job needs. Through the use of integral Switch Blocks in the various intersections and the Intelli-Track Rollers, the panels will steer to pre-selected parking areas automatically. All Corners and Intersections come with four drive-in alignment strips for each joint, and are pre-drilled for proper mounting to the substrate.
